Detailed Description

In the following description, numerous details are provided to provide a thorough understanding of the utility model. However, it will be understood by those skilled in the art that the following description illustrates preferred embodiments of the utility model by way of example only and that the utility model may be practiced without one or more of these details. Furthermore, some technical features that are known in the art have not been described in detail in order to avoid obscuring the utility model.

According to one aspect of the present utility model, a heating assembly is provided. The heating assembly may be used to heat a faucet. Referring to fig. 1-3 in combination, the heating assembly 100 may include an inlet fitting 110, an outlet fitting 120, and a heating body holder 130. The water inlet joint 110 may be provided with a hot water inlet port 111, and the water outlet joint 120 may be provided with a hot water outlet port 121. The heating body holder 130 may have a water inlet end 131 and a water outlet end 132 opposite along the central axis. The water inlet joint 110 may be connected to the water inlet end 131, and the water outlet joint 120 may be connected to the water outlet end 132. As shown in fig. 2, the water inlet joint 110 may be fixed to the water inlet end 131 of the bottom of the heating body bracket 130 by a fastener, such as a screw. The water outlet connector 120 may be fixed to the water outlet end 132 of the top of the heating body bracket 130 by a fastener such as a screw.

The heating assembly 100 may further include a hot water pipe 140 and a heating body 150. Both ends of the hot water pipe 140 may be connected to the hot water inlet port 111 and the hot water outlet port 121, respectively. Thereby, the hot water pipe 140 is fixed between the water inlet joint 110 and the water outlet joint 120, and completes waterway connection with the water inlet joint 110 and the water outlet joint 120. A heating body 150 may be provided around the hot water pipe 140 for heating the hot water pipe 140. The number of the heating body 150 may be one or a plurality. The heating body 150 may have a structure surrounding the hot water pipe 140. "encircling" includes continuously encircling and discretely encircling. In an embodiment in which the heating body 150 is one, the heating body 150 may continuously surround the hot water pipe 140. In embodiments where the heating body 150 is a plurality, the heating body 150 may continuously or discretely surround the hot water pipe 140. Alternatively, one or more heating bodies 150 may also semi-surround the hot water pipe 140. "semi-surrounding" includes surrounding one-half, more than one-half, or less than one-half of the circumference of the hot water pipe 140. That is, the heating body 150 may be provided at a side of the hot water pipe 140 to locally heat the hot water pipe 140. Alternatively, the heating body 150 may be closely attached to the hot water pipe 140 or may not be in direct contact with the hot water pipe 140, and may be spaced apart from each other by a certain distance. In short, the hot water pipe 140 may be within the heating range of the heating body 150. The heating body 150 may be fixed between the water inlet joint 110 and the water outlet joint 120. Alternatively, the heating body 150 may be fixed to the heating body holder 130, may be fixed to the water inlet joint 110 and the water outlet joint 120, or may be fixed to the hot water pipe 140. This may be related to the type of heating body 150, which will be described later.

The water inlet joint 110 may be injection molded, with a flow passage disposed therein. One end (e.g., a lower end) of the flow passage may be connected to a water supply pipe (not shown). The water supply pipe may be connected to a water source such as tap water, a water purifier, etc. The other end (e.g., upper end) of the flow passage may be connected to the hot water inlet port 111. The normal temperature water to be heated or the preheated hot water supplied from the water supply pipe may be supplied to the hot water pipe 140 via the water inlet joint 110. The water is heated by the heating body 150 while passing through the hot water pipe 140. The heated water may be delivered to the water outlet connection 120. The water outlet joint 120 may be connected to the water outlet nozzle 241. A sealing element can be arranged between the hot water pipe 140 and the hot water inlet port 111 and the hot water outlet port 121, or the sealing element can be sealed by sealant. The water outlet joint 120 may be injection molded, or may have a flow passage formed therein. One end of the flow passage may be connected to the hot water outlet port 121, and the other end may be connected to the water outlet nozzle 241.

In the heating assembly 100 provided by the present application, since the water inlet joint 110 and the water outlet joint 120 are respectively connected to both ends of the heating body support 130, the three can be connected into one integral piece, and both ends of the hot water pipe 140 are fixed to the integral piece by being connected to the water inlet joint 110 and the water outlet joint 120; furthermore, the heating body 150 may be fixed between the water inlet joint 110 and the water outlet joint 120. Thus, the heating assembly 100 can be pre-assembled, and the sealing performance between the hot water pipe 140 and the water inlet joint 110 and the water outlet joint 120 can also be tested before being mounted on the heating faucet, so that the problem of water leakage after being mounted in the heating faucet is avoided. After assembly of the heating assembly 100, it is generally not necessary to disassemble again. The assembled heating assembly 100 may be provided to a user as a finished product or may be assembled into a heating faucet at a later stage. Compared with the case where the existing heating assemblies are mounted to the heating faucet as the separate members, the quality problem can be prevented from being found after the heating assemblies 100 are mounted to the heating faucet by assembling and testing in advance, so that the case where the heating faucet is integrally disassembled can be avoided, and further the production cost can be reduced. In addition, the heating assembly 100 is assembled into the heating faucet after being assembled integrally, so that the assembly difficulty can be reduced, and the yield can be improved.

Illustratively, as shown in fig. 3, the hot water inlet port 111 and the hot water outlet port 121 may have a tubular shape extending toward each other, and both ends of the hot water pipe 140 may be respectively sleeved on the hot water inlet port 111 and the hot water outlet port 121. The heating body 150 may be a thick film heating body formed on the hot water pipe 140.

The hot water inlet 111 and the hot water outlet 121 are respectively inserted into two ends of the hot water pipe 140. Heating body 150 and hot water tube 140 may be considered as integral components. By way of example and not limitation, the hot water tube 140 may comprise a tubular structure of alumina ceramic, a thermally conductive, electrically insulating material. The thick film heating body is formed by printing a circuit on the outer surface of the hot water pipe 140 as a substrate. The thick film heating body is constructed to have a proper resistance value, and can perform rated heating of the hot water pipe 140 as a base body after the power supply of rated voltage or current is turned on, thereby heating the hot water flowing therethrough. Accordingly, the heating body 150 may be substantially a film body having a certain thickness and pattern formed on the surface of the hot water pipe 140.

The hot water inlet port 111 and the hot water outlet port 121 are respectively inserted into two ends of the hot water pipe 140, so that the movement of the hot water pipe 140 can be limited in the radial direction, and radial sealing is convenient to form, so that water leakage points are not easy to occur in the radial sealing. The two ends of the hot water pipe 140 are simultaneously propped against the water inlet joint 110 and the water outlet joint 120, so that the movement of the hot water pipe can be limited from the axial direction, no additional fixing structure is needed, and the cost is reduced. The thick film heating body may be directly formed on the outer surface of the hot water pipe 140 without a connection structure, so that the number of parts can be reduced and the radial size of the heating assembly 100 can be reduced. Compared with other types of heating bodies, the thick film heating body has lower cost, smaller thermal inertia and more excellent response speed and heating efficiency.

Illustratively, the heater fixture 130 may define a mounting cavity 133 therearound. Both the hot water pipe 140 and the heating body 150 may be disposed in the installation cavity 133. The hot water pipe 140 and the heating body 150 are spaced apart from the inner sidewall of the heating body holder 130. In order to prevent heat from escaping to the outer wall of the heating faucet to affect the user experience when heating hot water, a certain gap is formed between the inner wall of the heating body bracket 130 and the heating body 150, thereby reducing heat transfer. Thereby, a heat insulating chamber surrounding the heating body 150 is formed. On the other hand, the air in the insulating chamber may act as an electrical insulation. By designing the interval of a proper distance, it is possible to prevent the diameter of the heating assembly 100 from being too large and to prevent leakage or short circuit caused by breakdown of air between the heating body 150 and the heating body holder 130. In some embodiments, the interior of the heating assembly 100 may be maintained in a vacuum state, or after the heating assembly 100 is assembled to a heating faucet, the interior of the heating faucet may be maintained in a vacuum state to further reduce heat transfer and electrical leakage.

Illustratively, referring back to fig. 2, the heating body holder 130 may further be provided with a slot 134 penetrating the heating body holder 130 along the central axis, the slot 134 communicating with the installation cavity 133. The heating body holder 130 has a substantially C-shaped cross section. The heating body support 130 may be an extrusion, which is processed by extrusion. Providing the slot 134 can reduce the material cost of the heating body support 130 on the premise that the performance is substantially unchanged.

Illustratively, the heating assembly 100 may further include a wire harness (not shown) that may be connected to the heating body 150 through the slot 134. The heating body 150 may include a terminal 151 for connection with the outside. The terminal 151 may be connected to a power line, for example. Alternatively, the terminal 151 may be connected to an external signal line. By providing the slot 134, avoidance can be provided for the terminal 151 and the wire harness, the structure of the heating body support 130 is simplified, and the production cost is reduced. Also, when the heating assembly 100 is mounted to the heating faucet, the swivel arm 240 (see fig. 4) of the heating faucet may be further provided with a display screen, an operation panel, etc. electric elements, and their wiring harnesses may also be arranged to extend through the slot 134 to the bottom of the heating faucet, thereby saving space within the heating faucet.

Illustratively, the heating assembly 100 may further include a thermostat 160, the thermostat 160 being connected to the heating body bracket 130 at the slot 134. Referring to fig. 1-2 in combination, the thermostat 160 may include a mounting portion 161 and a detecting portion 162, and the mounting portion 161 may be fixed to the heating body stand 130. A portion of the sensing portion 162 of the thermostat 160 is in contact with the heating body 150 or the heating body 150 is closely spaced. When the temperature of the heating body 150 is too high during dry heating or failure, the temperature controller 160 can timely control the power supply circuit of the heating body 150 to be disconnected, so that accidents are prevented. The temperature controller 160 is usually a standard component, and may include a temperature control switch that is turned off when reaching a preset temperature, and its volume is generally slightly larger, and the temperature controller 160 is disposed at the slot 134, so that the heating assembly 100 may be made thinner to a certain extent, and the volume of the heating faucet is prevented from being excessively large. The contact area between the temperature controller 160 and the heating body bracket 130 is smaller, so that the heat of the heating body 150 can be further prevented from being transferred to the heating body bracket 130 through the temperature controller 160, the energy is saved, and the external heating of the heating faucet is avoided.

Illustratively, the water inlet fitting 110 may be provided with a flow sensor 170 for detecting the flow of water into the hot water pipe 140. The flow sensor 170 may include one or more of a volumetric flow sensor, a magnetic flow sensor, and the like. The flow information is acquired by the flow sensor 170, and may be provided to an internal or external control device, which calculates the power required to heat the water to a preset temperature and thus controls the power of the heating body 150. This allows the outlet water temperature of the heating assembly 100 to be precisely controlled.

Illustratively, the water inlet fitting 110 may be provided with a temperature sensor for detecting the temperature of water entering the hot water pipe 140. As the water to be heated entering the water inlet joint 110 may be preheated, the temperature may be indeterminate; or the temperature of the water to be heated is not determined due to seasonal variation, so that the temperature sensor is used for detecting the temperature of the water inlet and generating a water inlet temperature signal to be provided for the control device. Whereby the control means can precisely control the outlet water temperature of the heating assembly 100.

According to another aspect of the present utility model, there is provided a heating faucet, referring in combination to fig. 4-5, comprising a faucet body 210 and the heating assembly 100 described above, the heating assembly 100 being disposed within the faucet body 210.

Illustratively, the heating faucet may further include a normal temperature water pipe 220, as shown in fig. 2 and 5, a normal temperature water inlet 112 (fig. 2) may be provided on the water inlet joint 110, and a normal temperature water outlet 123 may be provided on the water outlet joint 120, as shown in fig. 8. Both ends of the normal temperature water pipe 220 are connected to the normal temperature water inlet port 112 and the normal temperature water outlet port 123, respectively. Illustratively, the normal temperature water pipe 220 is connected to the normal temperature water inlet 112 and the normal temperature water outlet 123 in a plugging manner. Thus, the normal temperature water pipe 220 may be fixed between the water inlet joint 110 and the water outlet joint 120 before being installed in the tap body 210, formed as a single piece with the heating assembly 100, and then assembled into the tap body 210, so that assembly and inspection are relatively simple. The heating faucet may provide warm water to a user while providing hot water. Illustratively, a mounting groove may be provided on an outer side surface of the heating body holder 130, and the normal temperature water pipe 220 may be mounted into the mounting groove so as to be fixed to the heating body holder 130. Alternatively, the normal temperature water pipe 220 may be fixed to the heating body bracket 130 in other manners.

For example, as shown in fig. 6, 8 and 9, the heating faucet may further include a water outlet swivel 230, and the water outlet swivel 230 may be rotatable about a central axis with respect to the water outlet joint 120. Referring to fig. 3 and 6 to 7, the water outlet joint 120 may be provided with a first water outlet 122a communicating with the hot water outlet 121 and a second water outlet 122b communicating with the normal temperature water outlet 123, and the second water outlet 122b may surround the first water outlet 122a. Referring to fig. 9, 10 and 11 in combination, the water outlet spin base 230 may be provided with a hot water spin base flow channel 231 and a normal temperature water spin base flow channel 232. The hot water swivel flow path 231 may have a first water inlet 231a and a third water outlet 231b, the normal temperature water swivel flow path 232 may have a second water inlet 232a and a fourth water outlet 232b, and the second water inlet 232a may surround the first water inlet 231a. The first water outlet 122a and the first water inlet 231a communicate with each other and are coaxially disposed with respect to the central axis, and the second water outlet 122b and the second water inlet 232a are connected to each other, see fig. 6. The third water outlet 231b and the fourth water outlet 232b may be connected to the water outlet nozzle 241 through a water outlet pipe and/or a water vapor separator, or may be directly connected to the water outlet nozzle 241.

Referring back to fig. 4, the heating faucet generally includes a fixed portion and a rotatable portion. The fixed portion may include, for example, a faucet body 210. The rotatable portion may include, for example, a swivel arm 240. The bottom of the tap body 210 may be provided with a mounting part 211, and the tap body 210 may be mounted to a desired location, such as a sink, by the mounting part 211. One end of the swivel arm 240 is rotatably connected to the tap body 210, for example, about a central axis, and the other end of the swivel arm 240 is provided with a water outlet nozzle 241. As shown in fig. 5, a heating assembly 100 may be disposed within the faucet body 210. The outlet swivel 230 may be disposed within the swivel arm 240. The outlet swivel 230 may communicate with the outlet nozzle 241. When the rotating arm 240 rotates relative to the tap body 210, the water outlet rotating seat 230 can rotate relative to the heating assembly 100, so that the position of the water outlet 241 can be adjusted, and the user can conveniently receive water at different positions.

As shown in fig. 6, the outlet swivel 230 may be plugged onto the outlet fitting 120. The second water outlet 122b and the second water inlet 232a may be directly inserted together, and the inner diameter of the second water inlet 232a may be larger than the outer diameter of the second water outlet 122b, so that the second water inlet 232a is sleeved outside the second water outlet 122 b. Of course, in an embodiment not shown, the inner diameter of the second water inlet may be smaller than the outer diameter of the second water outlet, which is sleeved outside the second water inlet.

The first water outlet 122a and the first water inlet 231a may be directly connected together as the second water outlet 122b and the second water inlet 232a are, or may be connected together by an additional connection pipe 250 as shown in fig. 6. Preferably, the inner wall and/or the outer wall of the plugging point can be sealed by adopting elastic materials, and a sealing ring 260 can be provided for sealing as shown in fig. 6.

Thus, the heating tap can provide hot water and warm water to the user, both of which can be taken from the water outlet nozzle 241. The heating faucet has simple structure and lower production cost.

Illustratively, the outlet fitting 120 may be secured to the faucet body 210. As shown in fig. 5 and 6, the water outlet joint 120 may be fixed to the tap body 210 by a fastener such as a screw. Since the water outlet joint 120 and other parts of the heating assembly 100 can be assembled in advance, the fixing of the heating assembly 100 can be completed without performing a complicated assembly step in the heating faucet. The direction of the screw fixing the water outlet joint 120 (and the assembled heating assembly 100) is identical to the direction of the screw fixing other parts of the heating faucet, and the assembly is simple.

In the description of the present utility model, it should be understood that the azimuth or positional relationships indicated by the azimuth terms such as "front", "rear", "upper", "lower", "left", "right", "transverse", "vertical", "horizontal", and "top", "bottom", etc., are generally based on the azimuth or positional relationships shown in the drawings, merely for convenience of describing the present utility model and simplifying the description, and these azimuth terms do not indicate and imply that the apparatus or elements referred to must have a specific azimuth or be constructed and operated in a specific azimuth, without limiting the scope of protection of the present utility model; the orientation terms "inner" and "outer" refer to the inner and outer relative to the outline of the components themselves.

For ease of description, regional relative terms, such as "over … …," "over … …," "on the upper surface of … …," "over," and the like, may be used herein to describe regional positional relationships of one or more components or features to other components or features shown in the figures. It will be understood that the relative terms of regions include not only the orientation of the components illustrated in the figures, but also different orientations in use or operation. For example, if the element in the figures is turned over entirely, elements "over" or "on" other elements or features would then be included in cases where the element is "under" or "beneath" the other elements or features. Thus, the exemplary term "above … …" may include both orientations "above … …" and "below … …". Moreover, these components or features may also be positioned at other different angles (e.g., rotated 90 degrees or other angles), and all such cases are intended to be encompassed herein.

It is noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of exemplary embodiments according to the present application. As used herein, the singular is also intended to include the plural unless the context clearly indicates otherwise, and furthermore, it is to be understood that the terms "comprises" and/or "comprising" when used in this specification are taken to specify the presence of stated features, steps, operations, components, assemblies, and/or combinations thereof.

It should be noted that the terms "first," "second," and the like in the description and the claims of the present application and the above figures are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that embodiments of the application described herein may be implemented in sequences other than those illustrated or otherwise described herein.

The present utility model has been illustrated by the above-described embodiments, but it should be understood that the above-described embodiments are for purposes of illustration and description only and are not intended to limit the utility model to the embodiments described. In addition, it will be understood by those skilled in the art that the present utility model is not limited to the embodiments described above, and that many variations and modifications are possible in light of the teachings of the utility model, which variations and modifications are within the scope of the utility model as claimed.
